been using the same bottle for over a year. insides are 302 stainless with a silicone gasket. I only keep water in it, nothing but water.
I wash it with a bottle scrub every four weeks.
- hot rinse (hottest from tap)
- soap wash (scrub)
- vinegar rinse with hot to steam
- rinse with cold until I don't smell vinegar
I rinse it every week using the same steps above, I just don't scrub it. I pay close attention to the gasket and make sure it gets a full exposure of the vinegar.
